The ADA, whose name I still can't remember, comes in for another round of I-know-best with the detectives, who talk her off the sex charges (since all she's got is a coached five-year-old with no physical evidence) and charge Eric on the child pornography found on his laptop, since that would get him off the streets and into a program.

So it's another round with Sean and Dana, who's completely falling apart, blaming herself for making her son who he is or, at the very least, bringing him into this world. She swears she doesn't know where he is, but Olivia and Fin (who's actually impressed by Elliot's restraint -- "I'd have done him," says Fin, if it had been his own kid) stake out her place and eventually catch her carrying a box somewhere.

The detectives follow her into a ground-floor apartment, and break into a run when they hear Dana scream. They find her cradling Eric's bloody, pale, lifeless body. "I killed him," she says over and over again, making Fin and Olivia look concerned, even though it's clearly self-blame and not an admission of guilt.

While the crime-scene guys go to work, Olivia quizzes Dana, who says she didn't know where Eric was until last night, when he called and left a message asking for help. She says she gave him $300 and told him he was on his own. She found the pornography on Eric's computer and never wanted to see him again. "I loved my son, and I'm glad he's dead!" she wails. Teri Polo nails it, gives me chills.

It takes an awful long time for Sean's name to be mentioned as a suspect, except the problem is that with all the blood, from eighteen stab wounds from several dull knives, there would have been too much transfer -- to clothes, car, home -- for Sean to clean up.

But Eric was also sodomized, with Corey's own baseball bat. That much, Sean cops to, but not the murder. He says he left Eric alive. And the ADA is suddenly a stickler for making sure the suspect is a lock for the crime, which she blames on Casey Novak lying to a judge. Warner finds some blood that doesn't belong to Eric, but to a diabetic. Hmmm. Maybe I should have mentioned that Jake Berlin did that finger-prick thing when the detectives interviewed him the first time. Not that it matters, since Jake's really the only other character from the episode, so this late in the game it's gotta be him.
